PAPER BOX.

SPECIFICATION forming part of Letters '.Patent No. 508,571, dated November 14, 1893.

Application flied Mani 25, 189s.

To all whom it may concern:

Be it known that I, JOHN J. HOFFMAN, of GlenCove, in the county of Queens and State of New York, have invented a new and useful Improvement in Paper Boxes, of which the following is a specification.

My invention relates to an improvement in paper boxes of the knock down type or where they may be adjusted from a flat or collapsed condition into an opened out or rectangular shape in cross section, with the object in View of keeping the folded ends of the box intact so far as the slitting of the corners or other parts of the flaps is concerned, and to this end I provide the ends of the box which are to be folded over to form the iiaps with certain creases so directed that the several parts will fold one upon another to make a complete closure of the end, either in connection with'a lining attached to and projecting from the end of the box or Without it.

In the accompanying drawings, Figure 1 is a View in perspective of one of the boxes with the body and iiaps'opened out. Fig. 2 is a similar View showing the ends partially folded'. Fig. 3 is aview in elevation, showing the ends folded with the exception of turning down the extended lining at one end. Fig. eis a partial elevation, showing the lining folded down. Fig. 5 is a top plan View of the box with the flaps in the position represented in elevation in Fig. 4., and Fig. is a plan View of the opposite end of the box at which the lining is omitted.

The body of the box may be formed of any suitable exible material, such as commonly employed for boxes. The flaps so far as they are formed by extended portions of the body A are quite similar at the opposite ends of the box and consist of side flaps, denoted by ct, formedl by creasing the side of the box a short distance back from its free edges so as to permit the aps a to hold over at right angles to the side of the body portion. The flaps adjacent to the flaps d are represented as a whole by B and are formedy by a creasing at substantially the same` distance from the end as the crease which forms the Iiap a andare further provided with creases b and b which extend from the extremities of Serial No. 467,587. (No modal.)

the transverse crease diagonally toward each other, meeting at a point b2 about midway of the edge of the side.

For convenience in filling the box, I provide one end with an extended lining portion C which may be glued or otherwise secured to the inner faces of the folding flaps at the end of the box, said extended portion O being adapted to fold along creases c, c extending from the point b2 to the free edge of the iiap so that when the aps a and b are folded down into positions at right angles to the body portions, the projecting lining portion C will be folded into flat, upwardly-extending folds, as represented in Fig. 3. To complete the folding of the end which hasa lining, the latter is turned down flat onto one of the folded side liaps, as shown in Fig. 4.

In practice, after the flaps ct and b at the bottom of the box are folded into the position shown in Fig. 6, they may be covered and a layerof paper glued thereto and the box may then be tilled, the lining portion C serving as a kind of extended hopper or spout for such purpose. When filled the top may be folded, as hereinabove described, the parts of the flap B upon opposite sides of the creases b and b being brought into'contact with each other and the extended lining portion C may then be folded over and an outside facing piece be then secured over the` top to hold the parts in folded position.

The above described structure is of great utility where finely pulverized material is to be packed, as theV closed corners of the iiap portions effectually prevent the sifting out or escape of such pulver-ized material.

What I claim is*- The herein described boxv having its folding aps at the ends united at the corners andan extended lining portion projecting from the edge of the folding or Hap portion, the iiaps and lining being creased to fold with the lining portion exterior to the flap portion of the body when infolded adjustment, substantially as set forth.

JOHN J.. HOFFMAN.'
